Certified Masks 25 Washes
Vieira & Faria presents its new certified reusable masks for 25 washes.
Before purchasing a social mask, confirm that it has been tested by a laboratory with recognized technical competence, which awards a seal and accompanied by an information leaflet.
There are many offers of social masks, but most of them are not properly validated by a laboratory accredited for this purpose. Which means that they will always provide some protection more than not wearing any mask, but, in the certified ones, the consumer has all the information related to the level of permeability of the fabric to air and its ability to filter particles, among other materials.
Deco / Proteste itself has already warned of the issue, stressing that "only those tested by laboratories with recognized technical competence, whose composition and maintenance obey a series of rules, guarantee the required quality".
